Collector Reducers - 1pr 2-1/2in to 2-1/2in

The Collector Reducers – 1 pair 2-1/2 inch to 2-1/2 inch – are heavy-duty exhaust system components designed for reducing collector pipe diameters while maintaining flow characteristics in high-performance applications. Featuring a 3-bolt flange connection, these steel reducers arrive as a matched pair with gaskets and hardware included, eliminating the need for separate component sourcing during installation or system maintenance.

Constructed from steel and finished with zinc oxide coating, these reducers provide corrosion resistance suitable for automotive exhaust environments where temperature cycling and moisture exposure demand durable metallurgy. The 3-bolt flange design ensures secure, repeatable connections across multiple installations or system configurations. Gaskets and fasteners included with the pair streamline assembly procedures and reduce assembly time in shop environments. The 2-1/2 inch inlet-to-outlet sizing accommodates standard collector piping diameter transitions common in performance exhaust header systems.

These reducers serve shops, fabricators, and automotive enthusiasts building or servicing performance exhaust systems where dimensional consistency and reliable flange connections are essential. Whether integrating into custom headers, modifying existing exhaust paths, or establishing compliant transition sections, the matched pair format ensures both sides of a dual-pipe system receive identical components. The zinc oxide finish supports longevity in high-heat applications while remaining cost-effective for production and prototype builds.

TacticalSurplusUSA stocks exhaust system components for builders and technicians requiring reliable, spec-compliant parts. This pair ships ready to install with all fastening hardware included, reducing procurement complexity for fabrication projects requiring multiple identical transition fittings.
